All Pokémon creatures and their moves are assigned certain types. Each type has several strengths and weaknesses in both attack and defense. In battle, you should use Pokémon and moves that have a type advantage over your opponent; doing so will cause much more damage than normal. A single-type advantage (for instance a Water attack against a Ground-type Pokémon) will net you double normal damage. The advantages also stack up , so a double-type advantage (for instance a Water attack against a Ground/Rock-type Pokémon) will net you quadruple damage. In both these cases you will see the message It's super effective! in-game after the attack. Conversely, a single- and double-type disadvantage will afflict half and a quarter normal damage respectively. Here you will see the message It's not very effective... in-game. Another advantage you can gain is Same Type Attack Bonus (STAB). As the name implies, this increases the power of the move if the attacking Pokémon has the same type as the move used (for example a Fire-type Pokémon using a Fire-type move). In this case the damage is times normal. Again this is added to any other advantages, so a Water-type Pokémon using a Water-type move against a Ground/Rock-type Pokémon will bag you six times (2×2×) normal damage! Type chart The full type chart here displays the strengths and weaknesses of each type. Look down the left hand side for the attacking type, then move across to see how effective it is against each Pokémon type. Note: this chart is for games from 2013 onwards - Pokémon X/Y, OR/AS, Pokémon GO and Sun/Moon. Type charts for older games have some minor differences - see below. Chart key
For instance I tried 600 mg of equipoise for 10 weeks and then went up to 1000 after reading about this being the sweet spot for lots of people. 1000 was way too much and I felt horrible, anxious with terrible blood pressure. The BP was high with 600 as well. After feeling so bad I thought I would try 250 mg a week to see how it affected my appetite. I did this for a couple months and it did help my appetite much better than 1000 mg and almost as well as 600 mg. could I grow faster with 600 mg? Maybe but having high blood pressure isn't worth it to me.
It should be noted that in theory if one was to consistently suppress your natural estrogen levels for a long period of time, this would negatively impact your health, including your cholesterol. Due to the ability of Letrozole- to inhibit estrogen so much, this should definitely be a concern to most users. However the research that has focused on the relationship between use of letrozole and cholesterol levels is rather inconsistent in it's findings. Many studies have concluded that the compound is detrimental to both a user's HDL and LDL cholesterol levels, while other research has found no link. Obviously individuals are best served to monitor their cholesterol while using any compound via blood tests however barring that, letrozole should simply not be run for extended periods of time if at all possible. Doing so could cause serious medical complications.
Along with the issues related to blood lipids is the fact that many users complain that their libido is dramatically reduced when using the compound. This is related to the fact that estrogen is partly responsible for the regulation of an individual's sex drive. Since Letrozole- is so potent it can often drive estrogen levels too low and this inhibits a user's libido. To avoid this users can lower dosages, but some anecdotally report that even extremely low doses of the drug can cause problems. If this is the case a less potent compound such as exemestane or anastrozole may be a more appropriate option.
